Abstract: 1,053,509. Turbine rotors; centrifugal compressors. ROLLS-ROYCE Ltd. Aug.6, 1965, No.33872/65. Headings F1C and F1T. To reduce turbulence a radial flow turbine or compressor rotor 14 has the radially inner portions of each radially extending vane 16 thicker than the radially outer portions thereof so that the effective flow cross sectional area of each flow passage between adjacent vanes varies at a substantially constant rate from the inlet to the outlet of the passage. The rotor 14 is formed in two parts connected by dowels 17 and the vanes 16 are thickened within the dotted area C. In the case of a radial inward flow turbine, the flow cross sectional area of a flow passage decreases at a constant rate along the length of the passage from the inlet to the outlet, as illustrated by graph B, Fig. 7 (not shown). In the case of a compressor, the flow is radially outwards with a constant rate of increase of the flow cross sectional area. The rotor may be used in a gas turbine engine.

Abstract: 1,054,927. Treating polyacrylonitrile fibres. COURTAULDS Ltd. Nov. 12, 1963 [Nov. 13, 1962], No. 42804/62. Heading B5B. Neon dried polyacrylonitrile fibres containing at least 80% by weight of acrylonitrile units, particularly 90 to 95% by weight of acrylonitrile units, are impregnated with an aqueous solution of an N-cyanoalkyl amide, or an N,N-bis-cyanoalkyl amide, the impregnated fibres are dried under conditions allowing them to shrink and are then stretched. The fibres may be brought into contact with steam, e.g. with steam at a pressure of 5 to 30 p.s.i.g. The cyanoalkyl amide may be a formamide or an acetamide. The alkyl group substituted by the cyano-group may contain from 1 to 3 carbon atoms. The aqueous solution may contain 1À5 to 4% by weight of amide and the proportion of amide left on the fibre may be at least 2%, e.g. 3 to 6% by weight. The fibres may be dried at 90‹ C. under zero tension. They may be stretched after drying by 15 to 85%, e.g. 30 to 60%. The stretching may be carried out at an elevated temperature, e.g. 100‹ to 110‹ C. The acrylonitrile may have been copolymerized with styrene, methyl acrylate, itaconic acid, methallyl sulphonic acid and its salts, vinyl acetate or vinyl pyridine. In all the examples, the polyacrylonitrile filaments treated are a copolymer of acrylonitrile, methyl acrylate and itaconic acid in the proportions 93 : 6 : 1 by weight and have been produced by extruding a solution of the polymer in a concentrated aqueous solution of sodium thiocyanate into a weaker solution of the same salt. The filaments are washed but not dried prior to the treatment with the aqueous amide solution, which imparts a high '' potential shrinkage " to the filaments. This shrinkage is defined as the shrinkage undergone by the filament when it is subjected to conditions allowing it to shrink freely, e.g. contacting the filament with boiling water or steam, under low tension or without tension.

A tunable maser comprises a body containing paramagnetic impurities in which fixed electron spins relax primarily by interactions with free conduction electrons and a negative temperature condition is obtained by raising the kinetic temperature of the conduction electrons in the presence of a magnetic field so that where T F  and T s  are the spin temperatures of the fixed and conduction electrons, T R  is the kinetic temperature of the conduction electrons, and g s  and g F  are the g values for the conduction and fixed electrons, g s  being much larger than g F  and of opposite sign. The output frequency depends upon the magnetic field strength. Suitable materials include indium antimonide, bismuth and zinc, and suitable paramagnetic materials are Fe<SP>3+</SP>, Gd<SP>3+</SP>, Mn<SP>2+</SP>, EU<SP>2+</SP> and Cr<SP>3+</SP>. The body may be a straightsided slab with ohmic contacts at each end, the magnetic field being applied perpendicular to the electric field. The temperature inversion may be increased by tapering the body or varying the degree of doping along its length and the body may be mounted in an r.f. cavity immersed in liquid helium. Fig. 7 shows an arrangement employing the Etting. hausen effect. The magnetic field is applied perpendicular to the major faces of slab 31 so that conduction electrons are deflected, resulting in an excess of high energy electrons at one side of the slab. Microwave emission is stimulated on this side of the slab, the other side being shielded by conductive foil 41 to prevent absorption of an equal amount of energy.

Abstract: 1,252,643. Roasting coffee beans and like granular food products. E. OSSWALD. 25 Feb., 1969 [29 Feb., 1968], No. 10047/69. Heading A2Q.  Coffee beans or other granular food products to be roasted are sealed, together with air or other gas, in a closed container system 1 which includes a blower 5 driven by a motor 6, a jacket pipe 10 the upper end of which is connected to the blower outlet, a return pipe 22 within the jacket pipe which is open to the interior of the jacket pipe at its lower end and connected at its upper end to the blower inlet, an oil burner 14 for heating the air or gas in the pipe 22, a separator 24 for separating out the beans entrained in the stream of air entering from pipe 22 and collecting them in a chamber 26 for return, via a pipe 20, to the lower end of the jacket pipe 10 for recirculation, and a flap valve 42 which is opened when the beans have been roasted to the desired degree for diverting the beans and hot gas into second closed container system 2 for cooling of the beans prior to separation, by a separator similar to that of the system 1, of any stones, nails, &c. which are ejected at an outlet 54, the beans being subsequently delivered by a cyclone separator 58, on opening a valve 60, to outlet 62. Since both systems are sealed during roasting of the beans by heating of the gas, pressure rises in the system 1 to about 24 atmospheres at which it remains until the beans and air are transferred to the cooling system 2 whereupon the cooling lowers the pressure. A colorimeter 38 may be disposed in the pipe 20 to sense when the beans are roasted to the desired degree and control the flap valve 42. Alternatively the degree of roasting may be judged manually using a sight glass. A humidity measuring device 41 controls a valve for supplying water to a nozzle 43 which injects the water into the pipe 22 to control humidity of the gas. The speed of motor 6 is preferably controlled by a pressure difference measuring device 40 to ensure that the grain follows the same path through the separator 24 irrespective of the pressure in the system 1. Alternatively device 40 may control the pitch of the blower fan blades. Skins and other light matter are trapped in an axial separator 31 and fall into a funnel 32. Means may be provided for evacuating the systems where a gas other than air is to be used. The flap valve 42, together with other valves 4, 9, 34, 52, 60 may be controlled by a time or by punched cards.

Case shift mechanism in an electric type-bar typewriter comprises a constantly oscillating member 20 which, when a shift key 46 is depressed, engages a hook 38 to draw the type basket downwardly into the upper case position, the basket being held in such position as long as the key is depressed by engagement of a pin 51 on a lever 12 which drives the type basket with a latching surface 50 of a locking lever 48. When the key 46 is released, a member 58 is moved so as to be engaged by a lug 22 on the oscillating member 20 which thereby disengages the pin 51 from the latching surface 50 to permit the basket to be returned to lower case position by a spring 8. In operation, depression of the key 46 acts through a lever 42 to pivot a lever 35 carrying the hook 38 upwardly into contact with the oscillating member 20 whereby the lever 35 is driven lengthwise, pivoting the lever 12 and thereby a lever 11 coupled to a type basket support member 5. The pin 51 on the lever 12 is then latched owing to spring bias on a lever 48 carrying the latch surface 50. Release of the key causes the lever 42 to return and a pin 61<1> thereon to cam the lever 58 into operative position for being struck by the member 20.

Abstract: 1,259,430. Transfer mechanisms. NATIONAL CASH REGISTER CO. 3 Nov., 1970 [14 Nov., 1969], No. 52126/70. Heading G4D. Simultaneous transfer in a full-bank cash register is effected by transfer segments which are moved to a first position while out of engagenient with the totalizer wheels and then allowed to return to a normal second position after re-engagement with the totalizer wheels. Amounts are set up on a keyboard in known manner and set actuators 116 differentially during the second half of a first machine cycle. In the first half of a second machine cycle totalizer wheels 16 are engaged with the actuators 116 to receive the entered amount as the actuators return to home position. Shaft 30 is moved at this time to disengage transfer segments 26 from engagement with the totalizer wheels and also from a fixed aligning bar 50. Passage of a wheel 16 from 9 to 0 causes a wide tooth 17 to rock a pawl 20 counter-clockwise, so moving a stud 22 from a lower to an upper notch of a pawl 23. The pawl 23 rocks to position a foot 28 into the path of a portion 29 of the transfer segment 26 of higher order. At the same time foot 24 of pawl 20 frees portion 25 of segment 26. At this time the totalizer wheels 16 are disengaged from the actuators 116 and engaged with the transfer segments 26. Then a bail 34 is rocked counter-clockwise away from surface 32 of each segment 26. Any transfer segment 26 which has been conditioned in the above manner is then rocked by its tension spring 33 to advance its associated wheel by one step. The shaft 30 then re-engages the transfer segments with bar 50.

Abstract: 1,265,947. Lubricator. DAIKIN KOGYO CO. Ltd. 28 May, 1970 [15 Oct., 1969], No. 25744/70. Heading F2A. A lubricant metering valve assembly has a manifold block unit coupled to at least one valve unit. The manifold block unit has two main passageways 35, 36 running through it, which communicate with a plurality of pairs of passageways 40a, 41a. The block also has a plurality of pairs of outlets 44a, 45a and a plurality of pairs of outlet passageways communicating with their respective outlets. The valve unit contains a distribution chamber 51a and a measuring chamber 50a, which contain respectively a valving piston 53a and a measuring piston 52a. The valving piston 53a has three lands. Each outer end of the distribution chamber communicates with the passageways 40a 41a of the manifold block unit through passageways 54, 55, and the central portion of the distribution chamber communicates with the outlet passageways 42a, 43a of the manifold block unit via passageways 56, 57. The outer ends of the distribution chamber and measuring chamber communicate with each other through oblique passageways 58, 59. When pressurized lubricant is introduced into one of the main passageways, the valving piston 52a slides in one direction thereby placing one side of the distribution chamber in communication with one side of the metering chamber, and the other side of the metering chamber in communication with a central portion of the distribution chamber. Pressurized lubricant flows into the measuring chamber thereby causing the measuring piston to slide in the same direction as the valving piston whereby a measured quantity of lubricant is expelled from the measuring chamber, and flows via the oblique passage 58 through the central portion of the distribution chamber to one of the outlet passages in the manifold block unit. The outlet passages may be placed in communication with each other and one of the outlets plugged so that lubricant issues from only one outlet of the manifold unit. The stroke of the measuring piston may be adjusted by means of nuts 92, 93 which limit the movement of the rod 81 carried by the piston.

Abstract: 1289165 Control of motors ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI 18 Nov 1969 [19 Nov 1968] 56408/69 Heading H2J [Also in Division G4] A position control system for a moving element 40 comprises a switch having contacts 16, 27, 28 via which a constant speed control voltage supplied by a coarse position measurement device 46, 56 is fed to a motor 47 driving the element or a decreasing speed control voltage supplied by a fine position measurement device 50, 57, 30 is fed to the motor. A conductor 1 is fed with a step voltage equal to the difference between a voltage supplied by the device 46 and a voltage supplied by a generator 54 corresponding to the required position towards which the moving element is being moved. The device 46 is a reactor which cooperates with a Gray coded measurement rule 45 to supply signals to a decoder 56. The step voltage, each step of which represents one coarse measurement position of the element 40 is fed to the motor 47 via a peak clipping amplifier 2, an inverting peak clipping amplifier 3 and a conductor 9, as that when the element 40 is at least a few coarse positions away from its required stopping position a constant voltage is supplied to the motor. On reaching a position corresponding to one coarse measurement position away from the required stopping position, a peak-clipping amplifier 4 provides an output to a relay coil 5 and the output of the amplifier 3 energizes a relay coil 6 thus closing contacts 10, 12 to energize a relay 14 which closes contacts 15, 17 but opens the contact 16. A condenser 18 enables the output voltage of the amplifier 3 to be stored on the input of an amplifier 19. A sinusoidal, decreasing control voltage supplied by the synchronous generator 50 is fed via a synchronous receiver 57, a discriminator 30, an amplifier 20, and the closed contact 15 to the input of the amplifier 19. If these two inputs to the amplifier 19 are the same, a relay coil 21 is de-energized and contacts 22 are closed thus causing a relay coil 23 to close the contact 28 and connect the sinusoidal control voltage to the motor via the conductor 9. A circuit including relay coils 7, 8, 31, 32, 38 snd contacts 24, 34-37, 39 ensures that the element 40 always moves towards its required stopping position. A control voltage generator 54 is connected to the conductor 1 and the receiver 57 and may comprise a set of ten position controllers the number of which corresponds to the number of significant figures characterizing the positions of the element 40. The control may be used in a glass cutter, in automatic warehouse cranes, in automatic parking or in a furnace charging machine.
